On HDCP disable, clear the repeater bit. This ensures if we connect a non-repeater sink after a repeater, the bit is in the state we expect.

This patch fixes a few bugs: 1- We weren't taking into account sha_leftovers when adding multiple ksvs to sha_text. As such, we were or'ing the end of ksv[j - 1] with the beginning of ksv[j] 2- In the sha_leftovers == 2 and sha_leftovers == 3 case, bstatus was being placed on the wrong half of sha_text, overlapping the leftover ksv value 3- In the sha_leftovers == 2 case, we need to manually terminate the byte stream with 0x80 since the hardware doesn't have enough room to add it after writing M0 The upside is that all of the HDCP supported HDMI repeaters I could find on Amazon just strip HDCP anyways, so it turns out to be _really_ hard to hit any of these cases without an MST hub, which is not (yet) supported. Oh, and the sha_leftovers == 1 case works perfectly!

Clang warns: drivers/gpu/drm/i915/display/intel_combo_phy.c:268:3: warning: variable 'ret' is uninitialized when used here [-Wuninitialized] ret &= check_phy_reg(dev_priv, phy, ICL_PORT_TX_DW8_LN0(phy), ^~~ drivers/gpu/drm/i915/display/intel_combo_phy.c:261:10: note: initialize the variable 'ret' to silence this warning bool ret; ^ = 0 1 warning generated. In practice, the bug this warning appears to be concerned with would not actually matter because ret gets initialized to the return value of cnl_verify_procmon_ref_values. However, that does appear to be a bug since it means the first hunk of the patch this fixes won't actually do anything (since the values of check_phy_reg won't factor into the final ret value). Initialize ret to true then make all of the assignments a bitwise AND with itself so that the function always does what it should do.

TGL made stepping a litte mess, workarounds refer to the stepping of the IP(GT or Display) not of the GPU stepping so it would already require the same solution as used in commit 96c5a15f ("drm/i915/kbl: Fix revision ID checks"). But to make things even more messy it have a different IP stepping mapping between SKUs and the same stepping revision of GT do not match the same HW between TGL U/Y and regular TGL. So it was required to have 2 different macros to check GT WAs while for Display we are able to use just one macro that uses the right revids table. All TGL workarounds checked and updated accordingly. v2: - removed TODO to check if WA 14010919138 applies to regular TGL. - fixed display stepping in regular TGL (Anusha) BSpec: 52890 BSpec: 55378 BSpec: 44455 Reviewed-by:

José Roberto de Souza authored
All GEN12 platforms supports PSR2 selective fetch but not all GEN12 platforms supports PSR2 hardware tracking(aka RKL). This feature consists in software programming registers with the damaged area of each plane this way hardware will only fetch from memory those areas and sent the PSR2 selective update blocks to panel, saving even more power. But as initial step it is only enabling the full frame fetch at every flip, the actual selective fetch part will come in a future patch. Also this is only handling the page flip side, it is still completely missing frontbuffer modifications, that is why the enable_psr2_sel_fetch parameter was added. v3: - calling intel_psr2_sel_fetch_update() during the atomic check phase (Ville) BSpec: 55229 Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Cc: Imre Deak <imre.deak@intel.com> Cc: Gwan-gyeong Mun <gwan-gyeong.mun@intel.com> Cc: Rodrigo Vivi <rodrigo.vivi@intel.com> Cc: Dhinakaran Pandiyan <dhinakaran.pandiyan@intel.com> Reviewed-by:

We usually assume that increasing PCI device revision ID's translates to newer steppings; macros like IS_KBL_REVID() that we use rely on this behavior. Unfortunately this turns out to not be true on KBL; the newer device 2 revision ID's sometimes go backward to older steppings. The situation is further complicated by different GT and display steppings associated with each revision ID. Let's work around this by providing a table to map the revision ID to specific GT and display steppings, and then perform our comparisons on the mapped values. v2: - Move the kbl_revids[] array to intel_workarounds.c to avoid compiler warnings about an unused variable in files that don't call the macros (kernel test robot).

The command register is the PCODE MBOX low register not the high one as described by the spec. This left the system with the TC-cold power state being blocked all the time. Fix things by using the correct register. Also to make sure we retry a request for at least 600usec, when the PCODE MBOX command itself succeeded, but the TC-cold block command failed, sleep for 1msec unconditionally after any fail. The change was tested with JTAG register read of the HW/FW's actual TC-cold state, which reported the expected states after this change. Tested-by:

The dependency between power wells is determined by the ordering of the power well list: when enabling the power wells for a domain, this happens walking the power well list forward, while disabling them happens in the reverse direction. Accordingly a power well on the list must follow any other power well it depends on. Since the TC AUX power wells depend on TC-cold being blocked, move the TC-cold off power well before all AUX power wells.

igt_mm_config() calls ilog2() on the (pseudo)random 21-bit number s>>12. Once in 2 million seeds, this is zero and ilog2 summons the nasal demons. There was an attempt to handle this case with a max(), but that's too late; ms could already be something bizarre. Given that the low 12 bits of s and ms are always zero, it's a lot simpler just to divide them by 4096, then everything fits into 32 bits, and we can easily generate a random number 1 <= s <= 0x1fffff.
